‘Dexter’ Season 7 First Look: Dexter vs. Debra

Dexter's sister knows his secret, but is she willing to keep it?

Last season on "Dexter," Michael C. Hall's title character finally tracked down the Doomsday Killer, Travis Marshall (Colin Hanks) and murdered him in an abandoned church. The only problem was that Dexter's sister, Debra Morgan (Jennifer Carpenter) saw everything… and now his secret is out.

Although "Dexter" season 7 won't kick off until September, TV Guide has debuted the first picture from the new season that depicts the immediate aftermath of the cliffhanger ending.

"Viewers might think we shy away from that moment of Debra walking in and seeing Dexter stabbing into Travis' chest, but it's just the opposite," noted "Dexter" executive producer Scott Buck. "She now has to deal with what she's seen and what she knows. And it forces him to defend and define himself."

Buck also addressed the controversial storyline that saw Debra develop romantic feelings for her adopted brother after a lifetime of platonic and one-sided friendship.

"It's ironic that people are fine with Dexter jabbing people in the heart but mortified by this romance," said Buck. "We're not shying away from those feelings of hers, either."

The TV Guide report also names Ray Stevenson's character as Sirko, but curiously describes him as a "Ukrainian strip club owner" rather than the "high-ranking member of an Eastern European crime ring" he was called in previous casting reports.

Earlier today, "Chuck" star Yvonne Strahovski was confirmed as a new member of the "Dexter" season 7 cast, where she will play Hannah McKay, a woman who is called into Miami Metro Homicide to help Dexter and the other investigators solve some cold cases. And if Hannah will be working with Dexter then it suggests that Debra is going to let his secret slide… at least for now.
